<p>PROBLEM TO BE SOLVED: To provide a super-high pressure water apparatus which can be simply constituted without using a complicated mechanism or a structure when a pressure is arbitrarily determined.SOLUTION: A super-high pressure water apparatus comprises: a high-pressure pump for feeding out water or a liquid in a superhigh-pressure state to water-discharge means; a motor or a drive source of the high-pressure pump; pressure detecting means for detecting the pressure of the superhigh-pressure liquid fed out from the high-pressure pump; set pressure inputting means for setting a desired pressure value of the superhigh liquid fed out from the high-pressure pump; and pressure control means for controlling the rotation frequency of the motor on the basis of the pressure information from the pressure detecting means and the desired pressure value set by the set pressure inputting means. The super-high pressure water apparatus is characterized in that the pressure of the liquid to be discharged from the high-pressure pump is controlled by controlling the rotation frequency of the high-pressure pump.</p> |
